TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 231,458, dated August24, 1880.

Application filed May 27, 1880.

To all whom @t may concern Be it known that I, JOHN H. STAPLES, of thecity and county of Worcester, and State of Massachusetts, have inventeda new and useful Improvement in Turbines; and I do hereby declare thesame to be describedin the following specification, and represented inthe accompanying drawings, of which- Figure l is a front elevation, Fig.2 a vertical and transverse section, and Fig. 3 a horizontal section, ofa turbine containing my invention, the nature of which is duly set forthin the claim or claims hereinafter presented. Fig. t is a side View ofthe turbine as it appears when detached from its chute.

In the said drawings, the turbine or wheel proper is shown at A as iiXedconcentrically upon an upright shaft, B, which at its lower end isstepped upon a pivot, a. The said pivot is sustained by a spider, C,indirectly supported by the annular chute-sustaining ring D. The saidannular chute E encompasses the wheel and conveys and directs the waterto its buckets b.

The chute is provided with a dome, F, having at its crown astuffing-box, G, for Athe shaft to revolve in. The cap c ot' thestuffingbox has a tubular extension, H, which projects up from it to analtitude above the water in the fiume, and opens at its lower end intothe Astuflingbox. The object of this eXtension H is to protect thebearing-surfaces of the shaft and box from water and enable the box tobe oiled through the extension.

The wheel A is composed of a shaft-supporting head, c, acyliudro-conical bucket-supporter, d, and a series of buckets, b, formedand arranged as represented.

The outer surface of the cylindro-conical supporter d, on which thebuckets are arranged, serves as a deflector of the water down upon thebuckets on it eseapingfrom the chute.

Between the chute and the wheel, and concentric With them, is theannular gate I, formed as shown, and supported by a series of rods, g,each of such rods passing up through the ring D, and one of a series oftubes, K, extending up from such ring to an altitude (No model.)

above the surface of the water in the ume. The ring D is to rest on thelicor of such iiume.

The hollow standards or tubes K answer as protections to the rods g,each of which at its upper part is furnished with a long screw, h, uponwhich two nuts, ik, are screwed. The lower of the said nuts rests on thetop ot the tube, one nut serving as a check-nut to the other. By meansof these screws and nuts the height of the gate is determined from timeto time relatively to the chute and buckets of the Wheel.

The ring D and the chute E have annular grooves formed in them, suchgrooves being shown in section at m m. in Fig. 2. They are to receive anannular packing, u, which, when the screws p, connecting the ring D andthe chute E, are screwed up, becomes compressed and forced against theouter periphery ot' the gate, and serves to make a water-tight jointabout the same.

What Iclaim as my invention is as follows, viz:

l. The turbine A, composed of the shaftsustaining head, thecylindro-conical bucketsupporter, and the series of buckets, arranged asset forth.

2. The chute E and annulus D, grooved, as described, and provided withthe annular packing n, in combination with the gate and the wheel,arranged as set forth.

3. The combination ofthe tubular standards K with the chute-support ringD, and the annular gate and its sustaining-screw rods and nuts, allbeing arranged substantially as set forth, and such gate being disposedwith respect to the turbine and its chute in manner as represented.

4. The combination of the tubular guard H, applied to the stutfngboxcap, as set forth, with the said stuffing-box and the wheel and itsshaft and the chute and its dome, such wheel and chute having an annulargate, and all being substantially as specified and represented.

JOHN H. STAPLES.
